Thanks to all for your responses. This is great news. The conference is held at a very small college (Cannington Agricultural College), and their technology (or at least what we have been allowed to use) is fairly, er, unimpressive. But it sounds like their equipment may work after all. I have till July to find out. Thanks again. ---- For past messages, visit the Screen-L Archives: http://bama.ua.edu/archives/screen-l.html
